Snape's Grudge

'Mr. Prongs agrees with Mr. Moony, and would like to add that Professor Snape is an ugly git.'
-- The Marauder's Map

Security is tightened, Hagrid is summoned to London with Buckbeak, Ron and Harry plan another visit to Hogsmeade despite Hermione’s appeals, Harry wears his invisibility cloak and while playing a trick on Malfoy and his goons is unmasked, rushing back to school only to be confronted by Snape, questioned and only saved by the arrival of Lupin.

Calendar and Dates

The chapter picks up at the end of the preceding chapter (late Saturday/ very early Sunday) on the night of the Gryffindor vs. Ravenclaw match) and ends on the Saturday of the school year's third Hogsmeade weekend.

Interesting facts and notes

'Mr. Prongs agrees with Mr. Moony, and would like to add that Professor Snape is an ugly git.'

One of the Frequently Asked Questions at JKR is, 'When the Marauder's Map is insulting Snape, how did Prongs write his insult as he's dead?' JKR's answer was, "Wizards have ways of making sure their voices are heard after their death[s] - think of Bertha Jorkins rising out of the Pensieve in [GF30], the Sorting Hat continuing to spout the wisdom of the Founders hundreds of years after their deaths, the ghosts walking around Hogwarts, the portraits of dead headmasters and mistresses in Dumbledore's office, not to mention Mrs. Black's portrait in number twelve, Grimmauld Place...there are other examples, too, of which the Marauder's Map is merely one. It is not really Prongs writing the insult to Snape, it is as though he left a magical recording of his voice within the map."

Exceptional character moments

Ron, enjoying all the attention he gets after being attacked.

Hagrid, giving Harry and Ron a talking-to about their priorities in how they've been treating Hermione.
